Cerebrolysin vs NA-Selank
A side-by-side research comparison of Cerebrolysin and NA-Selank across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Cerebrolysin | NA-Selank |
|---|---|---|
| Full name | Cerebrolysin (Brain-Derived Peptide Preparation) | N-Acetyl Selank (Acetylated Selank) |
| Category | Cognitive & Nootropic | Cognitive & Nootropic |
| Status | Investigational | Research compound |
| Mechanism | Contains fragments mimicking NGF, BDNF, GDNF, CNTF. Enhances synaptic plasticity, promotes neuronal sprouting, reduces amyloid-beta, and stabilizes calcium homeostasis. | Same tuftsin-derived mechanism as Selank with acetyl group providing protease resistance; modulates GABA, enhances BDNF. |
| Molecular weight | <10,000 Da (peptide fraction) | 793.91 Da |
| Half-life | 4-6 hours | ~5-10 minutes (effective 4-6 hours) |
| Bioavailability | High (IM/IV) | ~95% intranasal |
| Typical dose | 5-30 mL | 200-400 mcg |
| Frequency | Daily for 10-20 days | 1-2x daily |
| Route | Intramuscular or IV | Intranasal spray |
